would it also be possible to use the same reference panorama with pictures from anothr time position? As I already got a good reference Pano - but still would need to set a few CPs on other pictures ...?!

alright - at least there is a chance of doing so! ;-) Thank you!Biggest Problem is when distances to the Cameras differ .... like when I go inside a House ... before there are large distances between cam and objects - afterwards there is only a small distance left - so the stitchting TPL won't work correct ... would need to set different stitching TPLs for different timeframes ... but I guess there is no such functionality! :-/

Andreas,Not sure which rig you are using, but it helps to have the smallest possible lens-lens distance to at least minimize the parallax errors. I would also avoid situations where distances vary greatly (i.e. a tour through a house, going from a wide open space to a closed in space or similar). If you can't avoid it, edit your video, and cut it up into scenes that are meaningful: that way you can optimize each segment to minimize the parallax.

Right now we are using the H3PRO7 - guess this one should have the smallest lens-lens distance? Also tried to incline it 30° to have the 5 Main-Cameras aligned to the horizon.No chance to stitch a good looking walkthrough of our Bureau! :-/

Andreas,almost anything is stitchable, at least towards a result that is 'good enough' (since 'perfect' is not achievable), but I can't speak about the rig you are using. The design philosophy of our rig is using the smallest amount of cameras possible. I would say: keep trying, and modify your shooting style until it comes together.
